APPLICATION INFORMATION
When the resistor dissipates power, a temperature rise above the ambient temperature occurs, dependent on the thermal
resistance of the assembled resistor together with the printed circuit board. The rated dissipation applies only if the permitted
film temperature is not exceeded.
These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift
increasing over operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a
functional lifetime.

• The presented operation modes do not refer to different types of resistors, but actually show examples of different loads, that lead to
different film temperatures and different achievable load-life stability (drift) of the resistance value. A suitable low thermal resistance of the
circuit board assembly must be safeguarded in order to maintain the film temperature of the resistors within the specified limits. Please
consider the application note “Thermal Management in Surface-Mounted Resistor Applications” (www.vishay.com/doc?28844) for

DESCRIPTION
Production is strictly controlled and follows an extensive
set of instructions established for reproducibility. A
homogeneous film of metal alloy is deposited on a high
grade ceramic body (Al2O3) and conditioned to achieve the
desired temperature coefficient. Nickel plated steel
termination caps are firmly pressed on the metallised rods.
A special laser is used to achieve the target value by
smoothly cutting a helical groove in the resistive layer
without damaging the ceramics. The resistor elements are
covered by a protective coating designed for electrical,
mechanical and climatic protection. The terminations
receive a final pure matte tin on nickel plating. Four or five
color code rings designate the resistance value and
tolerance in accordance with IEC 60062 (1).
The result of the determined production is verified by an
extensive testing procedure performed on 100 % of the
individual resistors. This includes pulse load screening and
additional non-linearity screening for the elimination of
products with a potential risk of early life failures according
to EN 140401-803, 2.1.2.2. Only accepted products are laid
directly into the blister tape in accordance with
IEC 60286-3, Type 2a (1) or bulk case in accordance with
IEC 60286-6 (2).
ASSEMBLY
The resistors are suitable for processing on automatic SMD
assembly systems. They are suitable for automatic
soldering using wave, reflow or vapor phase as shown in
IEC 61760-1 (1). The encapsulation is resistant to all
cleaning solvents commonly used in the electronics
industry, including alcohols, esters and aqueous solutions.
The suitability of conformal coatings, potting compounds
and their processes, if applied, shall be qualified by
appropriate means to ensure the long term stability of the
whole system.
The resistors are completely lead (Pb)-free, the pure matte
tin plating provides compatibility with lead (Pb)-free and
lead containing soldering processes. Solderability is
specified for 2 years after production or requalification,
however, excellent solderability is proven after extended
storage in excess of 10 years. The permitted storage time is
20 years. The immunity of the plating against tin whisker
growth has been proven under extensive testing.

• Color code marking is applied according to IEC 60062 (1) in four bands (E24 series) or five bands (E96 or E192 series). Each color band
appears as a single solid line, voids are permissible if at least 2/3 of the band is visible from each radial angle of view. The last color band for
tolerance is approximately 50 % wider than the other bands. An interrupted yellow band between the 4th and 5th full band indicates TC25.
